A process is disclosed for removing finely distributed substances from a gaseous current. The substances are agglomerated by exposure to an acoustic field, the separated. Before exposure to the acoustic field, a seeding liquid is sprayed into the gaseous current to bind and absorb the substances to be removed. The seeding liquid is selected from the group that contains glycerol, aqueous solutions of potassium carbonate, magnesium oxide, sodium hydroxide, calcium hydroxide, sodium carbonate, hydrogen peroxide, hydrochloric acid, potassium permanganate, polyethylene glycol-dimethyl ether, mixtures of water and silicone oil, and aqueous solutions of beta-cyclodextrine and polyethylene glycol-dimethyl ether.
Selon un procédé d'élimination de substances finement réparties dans un courant de gaz, les substances sont agglomérées par exposition à un champ acoustique, puis séparées. Avant l'exposition au champ acoustique, un liquide d'ensemencement est atomisé dans le courant de gaz pour fixer et absorber les substances à éliminer. Le liquide d'ensemencement est sélectionné dans le groupe qui comprend le glycérol, des solutions aqueuses de carbonate de potassium, d'oxyde de magnésium, d'hydroxyde de sodium, d'hydroxyde de calcium, de carbonate de sodium, de peroxyde d'hydrogène, d'acide chlorhydrique, de permanganate de potassium de diméthyléther, de polyéthylèneglycol, les mélanges d'eau et d'huile de silicone et des solutions aqueuses de béta-cyclodextrine et de diméthyléther de polyéthylèneglycol.
